に渡(わた)ってAcross, Throughout, Extends, Over (a period of time or range)

Partnered with the case marking particle に, the う-Verb 渡(わた)る 'to cross' in its て-form highlights a span of something in regard to breadth, size, or time. This structure is often translated as either 'across (A)', 'throughout (A)', 'extending through (A)', or 'over the period of (A)'.

Like other verb structures that pair with nouns, the standard form may also be used when paired with a second noun, in order to modify that noun.

Coming from the meaning of 渡(わた)る 'to cross', this grammar pattern always expresses that something is either happening or exists 'all across (A)', or 'from the start to the finish'. Additionally, に渡(わた)って is considered quite formal, so will often be seen in articles or on the news.

Caution

As 渡(わた)る indicates a span of something that is being crossed, the 'span' must always be indicated clearly.
